Found a couple more dead hybrid bream today. Really big ones. Just had 4 inches of rain and the water is very turbid. I pulled up the turtle trap and had no turtles, but I had 3 bass,one about 2-1/2+ pounds, and 10 big bream. I examined them closely, all looked healthy to me. I know I should probably be taking out more fish, especially the bream. The pond has not been heavily fished and it's going on 3 years since stocking. I will test the water again to verify chemistry when it clears a little. Maybe I'm worrying for nothing.
